Pre-heat oven to 350°F.
Cut parallel lines down the length of your potatoes. Do not cut all the way through the potatoes.
Lay your potatoes in a greased cast iron skillet and brush them with oil. Sprinkle salt and pepper. Bake in the oven for 1 hour. You want to make sure your potatoes have fanned out.
Mix together your cream cheese, cream, jalapeños, grated mozzarella and sharp cheddar cheese, salt, and pepper.
Fill each pocket of the potato while alternating a slice of the bacon and a slice of the cheddar cheese. Top the potatoes with the cheese mixture.
Cover your potatoes with foil and put them in the oven for 20 minutes. Uncover potatoes and place back in the oven for an additional 5 minutes.
